Abstract

To improve the display quality of a display device, the display device includes a display section and a frame section surrounding a periphery of the display section. A substrate in the display device includes a conductor pattern constituting a circuit section and an insulating film serving as an organic film covering the conductor pattern. The insulating film extends to a peripheral edge of the substrate. A slit, which penetrates the insulating film in a thickness direction, is formed in a corner part of the insulating film. The slit is formed at a position not overlapping the circuit section.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A display device including a display section and a frame section surrounding the display section, the display device comprising:
 a first substrate; 
 a light shielding film provided on the first substrate; 
 a second substrate opposed to the first substrate; 
 a plurality of conductor patterns provided on the second substrate; and 
 a first insulation film covering the conductor patterns, 
 wherein a slit which penetrates the light shielding film in a thickness direction is formed in the light shielding film, 
 the light shielding film has a first portion and a second portion separated from the first portion by the slit, 
 the first portion is closer to an end portion of the first substrate than the second portion, 
 the end portion of the first substrate has a first end portion and a second end portion extending in a direction crossing the first end portion, 
 the first portion has a first extending portion along the first end portion and a second extending portion along the second end portion, 
 the first extending portion and the second extending portion are disposed at a corner portion of the first substrate in a plan view, and 
 the first extending portion is overlapped with the first end portion. 
 
     
     
       2. The display device according to  claim 1 ,
 wherein the second extending portion is overlapped with the second end portion. 
 
     
     
       3. The display device according to  claim 1 ,
 wherein a shape of the first portion is L-shaped. 
 
     
     
       4. The display device according to  claim 1 ,
 wherein the slit is formed along the first portion. 
 
     
     
       5. The display device according to  claim 1 ,
 wherein the slit is formed up to the second end portion in a plan view. 
 
     
     
       6. The display device according to  claim 1 ,
 wherein the slit is formed up to the first end portion in a plan view. 
 
     
     
       7. The display device according to  claim 1 ,
 wherein the frame section has a first virtual line extending along the first end portion and a second virtual line extending along the second end portion, 
 the first virtual line and the second virtual line are extensions of contour lines of the display section, and 
 the corner portion is a region surrounded by the first virtual line, the second virtual line, the first end portion, and the second end portion. 
 
     
     
       8. The display device according to  claim 1 , wherein the light shielding film is composed of an organic material. 
     
     
       9. The display device according to  claim 1 ,
 wherein the slit is formed only in the corner portion. 
 
     
     
       10. The display device according to  claim 1 ,
 wherein one of the conductor patterns is disposed at a position overlapping the slit. 
 
     
     
       11. The display device according to  claim 10 ,
 wherein a width of the one of the conductor patterns is larger than a width of the slit, in a plan view. 
 
     
     
       12. The display device according to  claim 1 ,
 wherein an edge of the light shielding film has a first edge and a second edge extending along the second end portion. 
 
     
     
       13. The display device according to  claim 12 ,
 wherein the slit is formed up to the first edge in a plan view. 
 
     
     
       14. The display device according to  claim 12 ,
 wherein the slit is formed up to the second edge in a plan view. 
 
     
     
       15. The display device according to  claim 12 ,
 wherein the first edge and the first end portion are aligned, and 
 the second edge and the second end portion are aligned.
